Description

Mobile ventilation, dust removal and temperature reduction integrated device for mine tunnel driving face

Technical field

The invention belongs to the technical field of mine safety and environmental engineering, and in particular relates to a mobile ventilation, dust removal and temperature reduction integrated device for the tunneling face of a mine underground.

Background technique

my country is rich in mineral resources, and coal, metals and other mineral resources are mostly mined underground. With the development of my country's economy, the demand for resources such as coal and metals is increasing. The shallow resources have basically been exploited, and underground mining needs to be further transferred to the deep. However, as the mining depth increases, the formation temperature increases accordingly, which leads to the problem of high temperature in the working environment during the mining of underground resources; especially in the tunnel driving face with poor ventilation, the heat from the rocks and working face equipment cannot be taken away in time , Resulting in the high temperature of the tunneling face as high as 40 ℃, which seriously exceeds the value specified in the national standard. The process of underground mining involves the blasting and crushing of a large amount of coal and rock, which will generate a large amount of coal dust and gun smoke. While underground mining is in a relatively closed space, ventilation can only be used to take away the dust and gun smoke generated from mining face. As for the poor ventilation of the single-headed roadway during the excavation process, a large amount of coal dust and gun smoke produced at the tunneling face will not be taken away in time, resulting in a serious excess of working dust concentration, and the gun smoke concentration can only reach the national standard. Prescribe the situation.

At this time, if the high-temperature air flow containing dust and cannon smoke is supplied to the tunneling work, it will further aggravate the deterioration of the working face environment, resulting in a higher air flow temperature. The emergence of problems such as higher concentrations of dust and cannon smoke. Excessive air current temperature can cause people to faint, high dust concentration can lead to the occurrence of people's pneumoconiosis, and high smoke concentration can lead to the risk of personnel poisoning. Therefore, how to reduce the air temperature, dust and gun smoke concentration of the tunnel driving face on the return air side, and reduce the harm to the human body, has become an urgent problem to be solved.
